The Growth Technology EC 1.413 300 ml calibration solution is a well-known standard solution with a fixed EC value for the calibration of EC measuring devices.
It is important to regularly calibrate your EC meters with Growth Technology solutions to ensure the accuracy of the measured EC values. Neglecting calibration can lead to crop failure and plant damage.
When calibrating, it is recommended to use only a small amount of the solution in a separate container, check the meter and then discard the solution to avoid contamination and extend the life of the calibration solution.
